In the display panel PNL, a plurality of data lines DL and a pluralityof gate lines GL can be disposed. A plurality of subpixels SP defined bythe plurality of data lines DL and the plurality of gate lines GL can bearranged in a matrix type in the display panel PNL.

In the display panel PNL, the plurality of data lines DL and theplurality of gate lines GL can be disposed to intersect each other. Forexample, the plurality of gate lines GL can be arranged in rows orcolumns, and the plurality of data lines DL can be arranged in columnsor rows. Hereinafter, for convenience of description, it is assumed thatthe plurality of gate lines GL are arranged in rows and the plurality ofdata lines DL are arranged in columns.

In addition to the plurality of data lines DL and the plurality of gatelines GL, other types of signal lines can be disposed in the displaypanel PNL according to a subpixel structure or the like. A driving powerline, a reference power line, or a common power line can be furtherdisposed in the display panel PNL.

Types of signal lines disposed in the display panel PNL can varydepending on the subpixel structure or the like. In the presentspecification, the signal line can be a concept including an electrodeto which a signal is applied.

The display panel PNL can include an active area A/A in which an image(video) is displayed and a non-active area N/A which is an area aroundthe active area N/A and in which an image is not displayed. Here, thenon-active area N/A is also referred to as a bezel area.

The plurality of subpixels SP for displaying an image are disposed inthe active area A/A.

A pad area to which a data driver DDR is electrically connected can bedisposed in the non-active area N/A. A plurality of data link lines forconnecting the pad area and the plurality of data lines DL can bedisposed in the non-active area N/A. Here, the plurality of data linklines can be portions of the plurality of data lines DL which extend tothe non-active area N/A or can be separate patterns electricallyconnected to the plurality of data lines DL.

In addition, gate driving-related lines, which transmit voltages(signals) necessary for gate driving to a gate driver GDR through a padpart to which the data driver DDR is electrically connected, can bedisposed in the non-active area N/A. For example, the gatedriving-related lines can include clock lines for transmitting clocksignals, gate power lines for transmitting gate voltages VGH and VGL,and gate driving control signal lines for transmitting various controlsignals necessary for generating scan signals.

The gate driver GDR can drive the plurality of gate lines GL byoutputting scan signals to the plurality of gate lines GL.

The controller CTR can control driving operations of the data driver DDRand the gate driver GDR by supplying various control signals DCS and GCSnecessary for driving operations of the data driver DDR and the gatedriver GDR. In addition, the controller CTR can supply image data DATAto the data driver DDR.

The controller CTR starts scanning according to a timing implemented ineach frame. The controller CTR converts image data input from anexternal device to be suitable for a data signal format used by the datadriver DDR, outputs the converted image data, and controls driving ofdata at an appropriate time according to scanning.

In order to control the data driver DDR and the gate driver GDR, thecontroller CTR can generate various control signals by receiving timingsignals such as a vertical synchronization signal Vsync, a horizontalsynchronization signal Hsync, an input data enable (DE) signal, and aclock signal CLK from an external device (for example, a host system).The controller CTR outputs the generated various control signals to thedata driver DDR and the gate driver GDR.

For example, in order to control the gate driver GDR, the controller CTRoutputs various gate control signals (GCSs) including gate start pulse(GSP), gate shift clock (GSC), and gate output enable (GOE) signals.

In addition, in order to control the data driver DDR, the controller CTRoutputs various data control signals (DCSs) including source start pulse(SSP), source sampling clock (SSC), and source output enable (SOE)signals.

The controller CTR can be a timing controller used in a typical displaytechnology. Alternatively, the controller CTR can be a control deviceincluding a timing controller to further perform other controlfunctions.

The controller CTR can be implemented as a separate component from thedata driver DDR. Alternatively, the controller CTR can be integratedwith the data driver DDR to be implemented as an integrated circuit.

The data driver DDR receives the image data DATA from the controller CTRand supplies data voltages to the plurality of data lines DL to drivethe plurality of data lines DL. Here, the data driver DDR is alsoreferred to as a source driver.

The data driver DDR can transmit and receive various signals to and fromthe controller CTR through various interfaces.

The gate driver GDR sequentially drives the plurality of gate lines GLby sequentially supplying scan signals to the plurality of gate linesGL. Here, the gate driver GDR is also referred to as a scan driver.

The gate driver GDR sequentially supplies scan signals having anon-voltage or an off-voltage to the plurality of gate lines GL under thecontrol of the controller CTR.

When a specific gate line is opened by the gate driver GDR, the datadriver DDR converts the image data DATA received from the controller CTRinto an analog data voltage and supplies the analog data voltage to theplurality of data lines DL.

The data driver DDR can be positioned at one side (for example, an upperor lower side) of the display panel PNL. However, the present disclosureis not limited thereto. For example, the data driver DDR can bepositioned at each of two sides (for example, the upper and lower sides)of the display panel PNL according to a driving method or a displaypanel design method.

The gate driver GDR can be positioned at one side (for example, a leftor right side) of the display panel PNL. However, the present disclosureis not limited thereto. For example, the gate driver GDR can bepositioned at each of two sides (for example, the left and right sides)of the display panel PNL according to a driving method or a displaypanel design method.

The data driver DDR can be implemented to include one or more sourcedriver integrated circuits (SDICs).

Each SDIC can include a shift register, a latch circuit, adigital-to-analog converter (DAC), an output buffer, and the like. Insome cases, the data driver DDR can further include one or moreanalog-to-digital converters (ADCs).

Each SDIC can be connected to a bonding pad of the display panel PNL ina tape automated bonding (TAB) type or a chip-on-glass (COG) type.Alternatively, each SDIC can be disposed directly on the display panelPNL. In some cases, the SDICs can be integrated and disposed on thedisplay panel PNL. In addition, each SDIC can be implemented as achip-on-film (COF) type. In this case, each SDIC can be mounted on acircuit film. Each SDIC mounted on the circuit film can be electricallyconnected to the data lines DL of the display panel PNL through thecircuit film.

The gate driver GDR can include a plurality of gate driving circuitsGDC. Here, the plurality of gate driving circuits GDC can eachcorrespond to one of the plurality of gate lines GL.

Each gate driving circuit GDC can include a shift register, a levelshifter, and the like.

Each gate driving circuit GDC can be connected to a bonding pad of thedisplay panel PNL in a TAB type or a COG type. In addition, each gatedriving circuit GDC can be implemented as a COF type. In this case, eachgate driving circuit GDC can be mounted on a circuit film. Each gatedriving circuit GDC mounted on the circuit film can be electricallyconnected to the gate lines GL of the display panel PNL through thecircuit film. In addition, each gate driving circuit GDC can beimplemented as a gate-in-panel (GIP) type and embedded in the displaypanel PNL.

In addition, a color filter may not be disposed in the secondsub-emission area EA22 of the second emission area EA2 disposed in the(N-1)^(th) row and the first sub-emission area EA21 of the secondemission area EA2 disposed in the N^(th) row. However, embodiments ofthe present disclosure are not limited thereto, and a color filter canbe disposed.

As described above, the emission areas emitting the same color light canbe disposed in the same column, and at least one repair pattern 240 canbe disposed between adjacent emission areas emitting the same colorlight.

Such a structure will be described in detail with reference to FIGS. 3and 4 as follows.

FIG. 3 is a cross-sectional view along line A-B of FIG. 2 , and FIG. 4is a cross-sectional view along line C-D of FIG. 2 .

Specifically, FIG. 3 is a cross-sectional view in a row direction whichillustrates a first sub-emission area EA31 of a third emission area EA3and a first sub-emission area EA41 of a fourth emission area EA4adjacent to the first sub-emission area EA31 of the third emission areaEA3.

FIG. 4 is a cross-sectional view in a column direction which illustratesa plurality of third emission areas EA3 and a circuit area included in anon-emission area NEA.

In the following descriptions, contents (configurations, effects, andthe like) that overlap those of the above-described embodiments can beomitted. In addition, in the following descriptions, the same referencenumbers can be used for components overlapping those of theabove-described embodiments.

First, referring to FIG. 3 , a display panel according to embodiments ofthe present disclosure can include an insulating layer 301 disposed on asubstrate 300.

Although the insulating layer 301 is illustrated as a single-layeredstructure in FIG. 3 , embodiments of the present disclosure are notlimited thereto, and the insulating layer 301 can have a multi-layeredstructure of two or more layers.

The insulating layer 301 can include an inorganic insulating material.For example, the insulating layer 301 can include at least one selectedfrom among silicon nitride (SiN_(x)), silicon oxide (SiO_(x)), andsilicon oxynitride (SiON).

Second and third color filters 212 and 213 can be disposed on theinsulating layer 301. An overcoat layer 302 can be disposed on thesecond and third color filters 212 and 213.

A first electrode 220 of an organic light-emitting element OLED can bedisposed on the overcoat layer 302. The first electrode 220 can includea transparent conductive material. For example, the first electrode 220can include at least one selected from among indium tin oxide (ITO),indium zinc oxide (IZO), and indium gallium zinc oxide (IGZO), but thepresent disclosure is not limited thereto.

A bank 250 can be disposed on the overcoat layer 302 and the firstelectrode 220. The bank 250 can overlap a portion of an upper surface ofthe overcoat layer 302 and a portion of an upper surface of the firstelectrode 220.

In an active area A/A, an area in which the first electrode 220 does notoverlap the bank 250 is an area included in the emission area, and anarea in which the bank 250 is disposed is the non-emission area NEA.

An organic light-emitting layer 360 can be disposed on the firstelectrode 220 and the bank 250.

A second electrode 370 can be disposed on the organic light-emittinglayer 360. The second electrode 370 can include a reflective conductivematerial. However, embodiments of the present disclosure are not limitedthereto.

The organic light-emitting element OLED including the first electrode220, the organic light-emitting layer 360, and the second electrode 370can emit W light. While the W light emitted from the organiclight-emitting element OLED passes through the color filters 212 and 213disposed in the sub-emission areas EA31 and EA41, specific color lightcan be emitted to the outside of the substrate 300.

For example, referring to FIG. 3 , B light can be emitted to the outsideof the substrate 300 from the first sub-emission area EA31 of the thirdemission area EA3 in which the second color filter 212 having a B coloris disposed, and G light can be emitted to the outside of the substrate300 from the first sub-emission area EA41 of the fourth emission areaEA4 in which the third color filter 213 having a G color is disposed.

Meanwhile, although FIG. 3 illustrates only a structure in which thesecond color filter 212 and the third color filter 213 are disposed torespectively correspond to the first sub-emission area EA31 of the thirdemission area EA3 and the first sub-emission area EA41 of the fourthemission area EA4, a cross-sectional structure of a second sub-emissionarea EA32 of the third emission area EA3 and a second sub-emission areaEA42 of the fourth emission area EA4 can also be the same as that ofFIG. 3 .

In addition, first and second sub-emission areas EA11 and EA12 of afirst emission area EA1 can also have a structure in which a substrate300, an insulating layer 301, a color filter 211, an overcoat layer 302,a first electrode 220, a bank 250, an organic light-emitting layer 360,and a second electrode 370 are sequentially stacked as shown in FIG. 3 .

First and second sub-emission areas EA21 and EA22 of a second emissionarea EA2 can have a structure in which a color filter is omitted fromthe structure shown in FIG. 3 . For example, the first and secondsub-emission areas EA21 and EA22 of the second emission area EA2 canhave a structure in which a substrate 300, an insulating layer 301, anovercoat layer 302, a first electrode 220, a bank 250, an organiclight-emitting layer 360, and a second electrode 370 are sequentiallystacked.

Referring to FIG. 4 , a display panel according to embodiments of thepresent disclosure includes a plurality of emission areas.

As shown in FIG. 4 , a transistor 405 can be disposed on a substrate300. At least one buffer layer can be disposed between the substrate 300and the transistor 405.

The transistor 405 can include an active layer, a gate electrode, asource electrode, and a drain electrode. In addition, the transistor 405can include a driving transistor for driving an organic light-emittingelement OLED.

An insulating layer 301 can be disposed on the substrate 300 on whichthe transistor 405 is disposed.

A second color filter 212 can be disposed on the insulating layer 301.However, a color filter may not be disposed on the insulating layer 301in a plurality of second emission areas EA2.

A repair pattern 240 can be disposed on the second color filter 212. Anovercoat layer 302 can be disposed on the substrate 300 on which thesecond color filter 212 and the repair pattern 240 are disposed.

A plurality of first electrodes 220 of organic light-emitting elementsOLED can be disposed on the overcoat layer 302, and a plurality ofconnection patterns 230 can be disposed.

A bank 250 can be disposed on the overcoat layer 302 on which the firstelectrode 220 and the connection pattern 230 are disposed.

An area in which the bank 250 is disposed in an active area is thenon-emission area NEA of the display panel, and an area in which thebank 250 is not disposed and the first electrode 220 is disposed is anemission area EA.

An organic light-emitting layer 360 and a second electrode 370 can besequentially disposed on the bank 250 and the first electrode 220.

The connection pattern 230 can be disposed between at least two firstelectrodes 220 and can be electrically connected to the at least twofirst electrodes 220.

The connection pattern 230 can be electrically connected to thetransistor 405 disposed in the non-emission area NEA through a contacthole CNT formed in the overcoat layer 302 and the insulating layer 301.

Specifically, one end portion of the connection pattern 230 can beelectrically connected to the first electrode 220 disposed in onesub-emission area (first sub-emission area EA31 of the third emissionarea), and the other end portion of the connection pattern 230 can beelectrically connected to the first electrode 220 disposed in anotheradjacent sub-emission area (second sub-emission area EA32 of the thirdemission area).

In other words, as shown in FIG. 4 , one end portion of one connectionpattern 230 can be in contact with the first electrode 220 in the firstsub-emission area EA31 of the third emission area EA3, and the other endportion thereof can be in contact with the first electrode 220 in thesecond sub-emission area EA42 of the third emission area EA3.

Due to the connection pattern 230, at least two sub-emission areas EA31and EA32 can be driven through one circuit area.

One connection pattern 230 can have a structure for being electricallyconnected to the first electrode 220 disposed in each of at least twosub-emission areas EA31 and EA32 emitting the same color light.

The connection pattern 230 can include a different material from thefirst electrode 220.

For example, the connection pattern 230 can include a reflectiveconductive material. The connection pattern 230 can include one selectedfrom among metals of aluminum (Al), gold (Au), silver (Ag), copper (Cu),tungsten (W), molybdenum (Mo), chromium (Cr), tantalum (Ta), andtitanium (Ti), or an an alloy thereof, but the present disclosure is notlimited thereto.

The connection pattern 230 can be disposed to overlap at least one colorfilter. The overcoat layer 302 can include holes 401 and 402 spacedapart from the contact hole CNT and formed in the non-emission area NEA.

The overcoat layer 302 can include the holes 401 and 402 overlapping thecolor filters 212 in areas corresponding to peripheral portions of thecolor filters 212.

The connection pattern 230 disposed on the overcoat layer 302 can beformed along the holes 401 and 402 formed in the overcoat layer 302. Forexample, the connection pattern 230 can also be disposed inside theholes 401 and 402 of the overcoat layer 320.

The first electrodes 220 disposed around the holes 401 and 402 of theovercoat layer 302 can be connected to the connection pattern 230. Forexample, a portion of a rear surface of the first electrode 220 can bein contact with the connection pattern 230.

Meanwhile, a portion of light emitted from the organic light-emittingelement OLED may not be extracted out of the substrate 300 but cantravel to another adjacent sub-emission area to be trapped inside thedisplay panel, which causes a problem in that the light efficiency ofthe display panel is lowered.

In the display device of embodiments of the present disclosure, sincethe connection pattern 230 including a reflective conductive material isdisposed along the holes 401 and 402 of the overcoat layer 302 formed atone sides of the sub-emission areas EA31 and EA32, light emitted fromthe organic light-emitting element OLED does not travel to anotheradjacent sub-emission area, and a direction of the light can be changedinto a direction toward the substrate 300. For example, since theconnection pattern 230 including a reflective conductive material isdisposed along the holes 401 and 402 of the overcoat layer 302 formed atone sides of the sub-emission areas EA31 and EA32, the connectionpattern 230 can be a reflective pattern for changing a direction oflight on at least one inclined surface of the holes 401 and 402.

For example, a portion of light emitted from the first sub-emission areaEA31 of one third emission area EA3 can pass through the first electrode220, the overcoat layer 302, the second color filter 212, and theinsulating layer 301 to be extracted out of the substrate 300.

Another portion of the light emitted from the first sub-emission areaEA31 of the third emission area EA3 can be reflected by the connectionpattern 230, which is positioned in the first hole 401 of the overcoatlayer 302 provided between the first sub-emission area EA31 of the thirdemission area EA3 and the circuit area for driving the firstsub-emission area EA31, to be extracted out of the substrate 300.

In addition, still another portion of the light emitted from the firstsub-emission area EA31 of the third emission area EA3 can pass throughan area corresponding to the second sub-emission area EA32 of anotheradjacent third emission area EA3 and can be reflected by the connectionpattern 230, which is positioned in the second hole 402 of the overcoatlayer 302 provided between the second sub-emission area EA32 of anotheradjacent third emission area EA3 and the circuit area for driving thesecond sub-emission area EA32, to be extracted out of the substrate 300.

As described above, since the first sub-emission area EA31 of the thirdemission area EA3 and the second sub-emission area EA32 of anotheradjacent emission area EA3 share one second color filter 212 and emitthe same color light, even when light emitted from the firstsub-emission area EA31 of the third emission area EA3 is emitted fromthe second sub-emission area EA32 of another adjacent emission area EA3due to the connection pattern 230 provided in the second hole 402 of theovercoat layer 302, it is possible to obtain an effect in which lightcan be emitted without color mixing.

In other words, since light emitted from the organic light-emittingelement OLED travels from one sub-emission area to another adjacentsub-emission area, it is possible to prevent a problem in that the lightefficiency of the display panel is lowered.

In addition, at least one repair pattern 240 can be disposed between atleast two sub-emission areas included in one emission area. In thiscase, the repair pattern 240 can be disposed on the color filter.

Specifically, referring to FIG. 4 , the repair pattern 240 can bedisposed between the second color filter 212 and the overcoat layer 302.

The repair pattern 240 is disposed in the non-emission area NEA betweenthe first sub-emission area EA31 of one third emission area EA3 and thesecond sub-emission area EA32 of another adjacent third emission areaEA3.

Here, a material of the repair pattern 240 can include a materialcorresponding to a material of the connection pattern 230. For example,the repair pattern 240 can include one selected from among metals ofaluminum (Al), gold (Au), silver (Ag), copper (Cu), tungsten (W),molybdenum (Mo), chromium (Cr), tantalum (Ta), and titanium (Ti), or anan alloy thereof, but the present disclosure is not limited thereto.

A process of manufacturing such a display panel will be described withreference to FIGS. 5 to 9 as follows.

Particularly, FIGS. 5 to 9 show schematic views illustrating amanufacturing process of forming the display panel shown in FIG. 2 .

Referring first to FIG. 5 , a transistor 405 can be disposed on asubstrate 300. An insulating layer 301 can be disposed on the substrate300 on which the transistor 405 is disposed.

A first color filter 211, a second color filter 212, and a third colorfilter 213 can be formed on the insulating layer 301.

A plurality of repair patterns 240 can be disposed on portions of uppersurfaces of the first to third color filters 211, 212, and 213. Forexample, as shown in FIG. 5 , one repair pattern 240 can be disposed onone color filter 211, 212, or 213.

Meanwhile, a color filter may not be disposed in a second emission area.In this case, as shown in FIG. 5 , the repair pattern 240 can bedisposed on the insulating layer 301.

Thereafter, as shown in FIG. 6 , an overcoat layer 302 can be disposedon the substrate 300 on which the repair patterns 240 are disposed.

A plurality of contact holes CNT can be formed in the overcoat layer302.

The contact hole CNT formed in the overcoat layer 302 can expose aportion of a surface of a source electrode or a drain electrode of atransistor (for example, a driving transistor) included in a circuitarea for driving each of emission areas EA1, EA2, EA3, and EA4.

In addition, the overcoat layer 302 can include a plurality of holes 401and 402 spaced apart from the contact hole CNT.

The plurality of holes 401 and 402 can be formed to correspond toperipheral areas of sub-emission areas EA11, EA12, EA21, EA22, EA31,EA32, EA41, and EA42 of the emission areas EA1, EA2, EA3, and EA4.

In the sub-emission areas EA11, EA12, EA31, EA32, EA41, and EA42 offirst, third, and fourth emission areas EA1, EA3, and EA4, the pluralityof holes 401 and 402 can be formed to expose portions of upper surfacesof the color filters 211, 212, and 213.

In addition, in the sub-emission areas EA21 and EA22 of a secondemission area EA2, the plurality of holes 401 and 402 can be formed toexpose portions of an upper surface of the insulating layer 301 disposedbelow the overcoat layer 302.

Thereafter, as shown in FIG. 7 , connection patterns 230 can be disposedon the overcoat layer 302.

The connection pattern 230 can be formed inside each of the contact holeCNT, the first hole 401, and the second hole 402 of the overcoat layer302.

The connection patterns 230 can extend from first sub-emission areasEA11, EA21, EA31, and EA41 of the emission areas EA1, EA2, EA3, and EA4to second sub-emission areas EA12, EA22, EA32, and EA42 of the emissionareas EA1, EA2, EA3, and EA4 through the circuit areas of the emissionareas EA1, EA2, EA3, and EA4.

The connection pattern 230 can be disposed only in a non-emission areaNEA of an active area A/A.

Next, as shown in FIG. 8 , a plurality of first electrodes 220 oforganic light-emitting elements can be disposed on the overcoat layer302.

The first electrodes 220 can overlap the sub-emission areas EA11, EA12,EA21, EA22, EA31, EA32, EA41, and EA42 of the emission areas EA1, EA2,EA3, and EA4 and can overlap portions of the non-emission area NEA.

In the non-emission area NEA, each of the first electrodes 220 can beconnected to the connection pattern 230.

Accordingly, as shown in FIG. 8 , the first electrodes 220 of theorganic light-emitting elements disposed to correspond to thesub-emission areas can be electrically connected to the circuit areasthrough the connection patterns 230.

Thereafter, as shown in FIG. 9 , a bank 250 can be formed to correspondto the non-emission area NEA. The bank 250 can be formed to overlap theconnection pattern 230 and the repair pattern 240.

When a foreign material is generated on the display panel having such astructure, the sub-emission area is repaired through the repair pattern240, thereby preventing the visibility of the display panel from beingdecreased even when the foreign material is present.

This will be described with reference to FIGS. 10 to 12 as follows.

FIG. 10 is a plan view illustrating a case in which a foreign materialis present on a connection pattern in the structure of FIG. 2 , and FIG.11 shows views illustrating a repairing method in a case in which aforeign material is present on the connection pattern. FIG. 12 showsviews illustrating emission states when a display panel is driven afterthe display panel having structures of FIGS. 10 and 11 is repaired.

Referring to FIGS. 10 and 11 , in a process of manufacturing a displaypanel according to embodiments of the present disclosure, a problem inthat a foreign material 1000 is formed on a connection pattern 230 mayoccur.

When the foreign material 1000 is present on the connection pattern 230,a current is concentrated in the foreign material 1000, and thus abright spot defect may be caused in sub-emission areas electricallyconnected to the connection pattern 230.

For example, when the foreign material 1000 is present on the connectionpattern 230 in an area between a contact hole CNT and a firstsub-emission area EA31 of a third emission area EA3 positioned in anN^(th) row, a bright spot defect may occur in the first sub-emissionarea EA31 of the third emission area EA3 in the N^(th) row.

In this case, as shown in FIG. 11 , a laser is irradiated in a directionfrom a rear surface of a substrate 300 toward the connection pattern 230to cut (disconnect) the connection pattern 230 disposed in the N^(th)row (Step 1).

In this case, a cutting position of the connection pattern 230 can be aposition between the foreign material 1000 and the first sub-emissionarea EA31 of the third emission area EA3 positioned in the N^(th) row.

As described above, by cutting the connection pattern 230, an organiclight-emitting element OLED disposed in the first sub-emission area EA31of the third emission area EA3 disposed in the N^(th) row can beelectrically disconnected from a circuit area disposed in the N^(th)row.

Accordingly, since a voltage cannot be supplied to the organiclight-emitting element OLED disposed in the first sub-emission area EA31of the third emission area EA3 disposed in the N^(th) row, even when thethird emission area EA3 in the N^(th) row enters an on state, the firstsub-emission area EA31 may not emit light.

For example, referring to FIG. 12 , after the connection pattern 230 iscut, even when all sub-emission areas disposed in the N^(th) row emitlight, a first sub-emission area (sub-emission area positioned in theN^(th) row and an M^(th) column) of the third emission area EA3 disposedin the N^(th) row may not emit light.

Thus, as shown in FIG. 11 , a laser is irradiated toward the rearsurface of the substrate 300 toward a repair pattern 240 to weld therepair pattern 240 positioned at a boundary between an (N-1)^(th) rowand the N^(th) row, thereby connecting the repair pattern 240 to a firstelectrode 220 of a second sub-emission area EA32 of the third emissionarea EA3 in the (N-1)^(th) row and a first electrode 220 of the firstsub-emission area EA31 of the third emission area EA3 in the N^(th) row(Step 2).

For example, the first sub-emission area EA31 of the third emission areaEA3 positioned in the N^(th) row can be electrically connected to acircuit area for driving the third emission area EA3 through the firstelectrode 220 of the second sub-emission area EA32 of the third emissionarea EA3 in the (N-1)^(th) row.

Accordingly, as shown in FIG. 12 , among the first sub-emission areasEA31 of the third emission areas EA3 positioned in the N^(th) row, thefirst sub-emission area EA31 of the third emission area EA3 connected tothe circuit area of the third emission area EA3 positioned in the(N-1)^(th) row through a welding process can emit light when a voltageis applied to the (N-1)^(th) row rather than the N^(th) row.

As described above, even when the foreign material 1000 is present onthe connection pattern 230, a defect of a specific sub-emission area canbe prevented, and the specific sub-emission can be repaired.

In addition, as shown in FIGS. 2 to 12 , in a display device accordingto embodiments of the present disclosure, one emission area can includeat least two sub-emission areas.

Even when a foreign material is present in a circuit area disposed inone row, at least two sub-emission areas are darkened and thenelectrically connected to a circuit area disposed in another adjacentrow, thereby repairing the darkened sub-emission area.

As described above, since one emission area is divided into at least twosub-emission areas, darkening and repairing can be performed on at leastone sub-emission area.

Accordingly, a first sub-emission area EA31 of a third emission area EA3disposed in an N^(th) row and an M^(th) column can be darkened, and afirst electrode 220 of a second sub-emission area EA32 of a thirdemission area EA3 disposed in an (N-1)^(th) row and the M^(th) columncan be electrically connected to a first electrode 220 of the firstsub-emission area EA31 of the third emission area EA3 disposed in theN^(th) row and the M^(th) column through a repair pattern 240 so thatthe first sub-emission area EA31 of the third emission area EA3 disposedin the N^(th) row and the M^(th) column can emit light when the thirdemission area EA3 disposed in the (N-1)^(th) row and the M^(th) columnemits light.

Even when it is desired to emit light from a third emission area EA3disposed in an (N-1)^(th) row and an M^(th) column, and it is notdesired to drive a third emission area EA3 disposed in an N^(th) row andthe M^(th) column, a repaired sub-emission area disposed in the N^(th)row and the M^(th) column can be driven concurrently when the thirdemission area EA3 disposed in the (N-1)^(th) row and the M^(th) columnis driven.

However, in a display panel according to embodiments of the presentdisclosure, since one emission area is divided into at least twosub-emission areas, an area of a repaired emission area can be reduced.

For example, when one emission area is not divided into a plurality ofsub-emission areas or a plurality of sub-emission areas are notelectrically connected through a connection pattern, an entire thirdemission area EA3 can be driven by a circuit area disposed in an(N-1)^(th) row and an M^(th) column when a foreign material is presentin the circuit area disposed in an N^(th) row and the M^(th) column. Asdescribed above, even when driving of an N^(th) row and an M^(th) columnis not desired, since an entire third emission area EA3 positioned inthe N^(th) row and the M^(th) column emits light, the visibility of adisplay panel can be lowered.

On the other hand, in a display panel according to exemplary embodimentsof the present disclosure, when repairing is performed due to a foreignmaterial present in a circuit area disposed in an N^(th) row and anM^(th) column, since a portion of a third emission area EA3 (forexample, one sub-emission area) is driven by a circuit area disposed inan (N-1)^(th) row and the M^(th) column, even when driving of the N^(th)row and the M^(th) column is not desired, an emission area with arelatively small area emits light, thereby improving the visibility ofthe display panel.

FIG. 13 shows diagrams illustrating a structure of a subpixel when aforeign material is present on a connection pattern of a display panelhaving the structure of FIG. 2 .

Referring to FIG. 13 , each subpixel SP in an organic light-emittingdisplay panel PNL can further include a second transistor T2 whichtransmits a data voltage Vdata to a first node N1 corresponding to agate node of a driving transistor T1 and a storage capacitor Cst whichmaintains the data voltage Vdata corresponding to an image signalvoltage or a voltage corresponding thereto for one frame time.

At least two organic light-emitting elements OLED included in onesubpixel SP each include a first electrode (anode or cathode), anorganic layer including at least one light-emitting layer, and a secondelectrode (cathode or anode).

As an example, a ground voltage EVSS can be applied to the secondelectrode of the organic light-emitting element OLED.

The driving transistor T1 supplies a driving current to the organiclight-emitting element OLED to drive the organic light-emitting elementOLED. The driving transistor T1 has the first node N1, a second node N2,and a third node N3.

The meaning of “nodes” of the first to third nodes N1, N2, and N3 can bepoints, electrode(s), or line(s) having the same electrical state.

Each of the first node N1, the second node N2, and the third node N3 caninclude one or more electrodes.

The first node N1 of the driving transistor T1 can be a nodecorresponding to a gate node and can be electrically connected to asource node or a drain node of the second transistor T2.

The second node N2 of the driving transistor T1 can be electricallyconnected to a first electrode 220 of the organic light-emitting elementOLED and can be a source node or a drain node.

The third node N3 of the driving transistor T1 can be a node to which adriving voltage EVDD is applied, can be electrically connected to adriving voltage line DVL that supplies the driving voltage EVDD, and canbe a drain node or a source node.

The driving transistor T1 and the second transistor T2 can beimplemented as an n-type or a p-type.

The second transistor T2 can be electrically connected between a dataline DL and the first node N1 of the driving transistor T1 and can becontrolled by a scan signal SCAN that is applied to a gate node thereofthrough a gate line.

The second transistor T2 can be turned on by the scan signal SCAN totransmit the data voltage Vdata supplied from the data line DL to thefirst node N1 of the driving transistor T1.

The storage capacitor Cst can be electrically connected between thefirst node N1 and the second node N2 of the driving transistor T1.

The storage capacitor Cst is not a parasitic capacitor (for example, Cgsor Cgd) which is an internal capacitor present between the first node N1and the second node N2 of the driving transistor T1 and is an externalcapacitor which is intentionally designed outside the driving transistorT1.

A third transistor T3 can be electrically connected between the secondnode N2 of the driving transistor T1 and a reference voltage line RVLand can be controlled and turned on/off by a second scan signal SCAN2that is applied to a gate node thereof.

A drain node or source node of the third transistor T3 can beelectrically connected to the reference voltage line RVL, and the sourcenode or drain node of the third transistor T3 can be electricallyconnected to the second node N2 of the driving transistor T1.

As an example, the third transistor T3 can be turned on in a displaydriving period and can be turned on in a sensing driving period forsensing a characteristic value of the driving transistor T1 or acharacteristic value of the organic light-emitting element OLED.

The third transistor T3 can be turned on by the second scan signal SCAN2according to a corresponding driving timing (for example, a displaydriving timing or an initialization timing within a sensing drivingperiod) and can transmit a reference voltage Vref supplied to thereference voltage line RVL to the second node N2 of the drivingtransistor T1.

In addition, the third transistor T3 can be turned on by the second scansignal SCAN2 according to a corresponding driving timing (for example, asampling timing within a sensing driving period) and can transmit avoltage of the second node N2 of the driving transistor T1 to thereference voltage line RVL.

In other words, the third transistor T3 can control a voltage state ofthe second node N2 of the driving transistor T1 or can transmit thevoltage of the second node N2 of the driving transistor T1 to thereference voltage line RVL.

Here, the reference voltage line RVL can be electrically connected to anADC which senses a voltage of the reference voltage line RVL andconverts the sensed voltage into a digital value to output sensing dataincluding the digital value.

The ADC can be included in an SDIC implementing a data driver DDR.

The sensing data output from the ADC can be used to sense thecharacteristic value (for example, a threshold voltage or mobility) ofthe driving transistor T1 or the characteristic value (for example, athreshold voltage) of the organic light-emitting element OLED.

Each of the driving transistor T1, the second transistor T2, and thethird transistor T3 can be an n-type transistor or a p-type transistor.

Meanwhile, the first scan signal SCAN1 and the second scan signal SCAN2can be separate gate signals. In this case, the first scan signal SCAN1and the second scan signal SCAN2 can be respectively applied to the gatenode of the second transistor T2 and the gate node of the thirdtransistor T3 through different gate lines.

In some cases, the first scan signal SCAN1 and the second scan signalSCAN2 can be the same gate signal. In this case, the first scan signalSCAN1 and the second scan signal SCAN2 can be commonly applied to thegate node of the second transistor T2 and the gate node of the thirdtransistor T3 through the same gate line.

The connection pattern 230 can serve to electrically connect thesub-emission areas of each of the emission areas EA1, EA2, EA3, and EA4to the circuit area.

The connection pattern 230 can be electrically connected to a transistorpositioned in the circuit area through a contact hole CNT formed in aninsulating layer disposed below the connection pattern 230.

In addition, the connection patterns 230 can include first connectionpatterns 1431 connected to the first sub-emission areas EA11, EA21,EA31, and EA41, second connection patterns 1432 connected to the secondsub-emission areas EA21, EA22, EA32, and EA42, third connection patterns1433 connected to the third sub-emission areas EA13, EA23, EA33, andEA43, and fourth connection patterns 1434 connected to the fourthsub-emission areas EA14, EA24, EA34, and EA44.

The connection pattern 230 can include an area 1451 (hereinafter,referred to as a first area) which is formed integrally with the firstand third connection patterns 1431 and 1433 and are disposed at one sideof the first and third sub-emission areas in the first sub-row of eachof the emission areas EA1, EA2, EA3, and EA4. In addition, theconnection pattern 230 can include an area 1452 (hereinafter, referredto as a second area) which is formed integrally with the second andfourth connection patterns 1432 and 1434 and are disposed at one side ofthe second and fourth sub-emission areas in the second sub-row of eachof the emission areas EA1, EA2, EA3, and EA4.

Furthermore, the connection pattern 230 can include at least onereflective pattern 1450 disposed between adjacent sub-emission areas inthe same sub-row of each of the emission areas. Specifically, in thesame sub-row, the reflective pattern 1450 can be disposed betweensub-emission areas emitting the same color light. The reflective pattern1450 can be formed integrally with the first area 1451 or can be formedintegrally with the second area 1452.

For example, as shown in FIG. 14 , at least one reflective pattern 1450can be disposed between the first sub-emission area EA11 and the thirdsub-emission area EA13 disposed in the first sub-row of the firstemission area EA1.

In addition, at least one reflective pattern 1450 can be disposedbetween the second sub-emission area EA12 and the fourth sub-emissionarea EA14 disposed in the second sub-row of the first emission area EA1.

In other words, the connection pattern 230 can include the first tofourth connection patterns 1431, 1432, 1433, and 1434, the first area1451, the second area 1452, and the reflective pattern 1450.

Such a structure will be described in detail with reference to FIGS. 15and 16 as follows.

FIG. 15 is a cross-sectional view along line G-H of FIG. 14 , and FIG.16 is a cross-sectional view along line I-J of FIG. 14 .

Specifically, FIG. 15 is a cross-sectional view in a row direction whichillustrates a first and third sub-emission areas EA31 and EA33 of athird emission area EA3 and a first and third sub-emission areas EA41and EA43 of a fourth emission area EA4 adjacent to the third emissionarea EA3.

FIG. 16 is a cross-sectional view in a column direction whichillustrates the first and second sub-emission areas EA31 and EA32 of thethird emission area EA3 and a circuit area included in a non-emissionarea NEA.

In the following descriptions, contents (configurations, effects, andthe like) that overlap those of the above-described embodiments can beomitted. In addition, in the following descriptions, the same referencenumbers can be used for components overlapping those of theabove-described embodiments.

First, referring to FIG. 15 , an insulating layer 301 can be disposed ona substrate 300, second and third color filters 212 and 213 can bedisposed on the insulating layer 301, and an overcoat layer 302 can bedisposed on the second and third color filters 212 and 213.

A plurality of first electrodes 220 disposed to correspond tosub-emission areas EA31, EA33, EA41, and EA43 can be disposed on theovercoat layer 302.

In addition, the overcoat layer 302 can include one or more third holes1501 formed therein.

The third hole 1501 can be formed between sub-emission areas emittingthe same color light.

A reflective pattern 1450 can be disposed in the third hole 1501.

The reflective pattern 1450 can include a reflective conductivematerial. For example, the reflective pattern 1450 can include oneselected from among metals of aluminum (Al), gold (Au), silver (Ag),copper (Cu), tungsten (W), molybdenum (Mo), chromium (Cr), tantalum(Ta), and titanium (Ti), or an an alloy thereof, but the presentdisclosure is not limited thereto.

A portion of the reflective pattern 1450 disposed between the firstemission area EA31 and the third sub-emission area EA33 of the thirdemission area EA3 can be in contact with a portion of the firstelectrode 220 disposed in the first sub-emission area EA31 of the thirdemission area EA3, and another portion of the reflective pattern 1450can be in contact with a portion of the first electrode 220 disposed inthe third sub-emission area EA33 of the third emission area EA3.

In addition, a portion of the reflective pattern 1450 disposed betweenthe first emission area EA41 and the third sub-emission area EA43 of thefourth emission area EA4 can be in contact with a portion of the firstelectrode 220 disposed in the first sub-emission area EA41 of the fourthemission area EA4, and another portion of the reflective pattern 1450can be in contact with a portion of the first electrode 220 disposed inthe third sub-emission area EA43 of the fourth emission area EA4.

As described above, since the reflective pattern 1450 is disposedbetween the sub-emission areas emitting the same color, a portion oflight emitted from the sub-emission area reaches the reflective pattern1450 and is reflected toward the substrate 300, thereby increasing anamount of light extracted out of the substrate 300.

In addition, a bank 250 can be disposed on the overcoat layer 302 onwhich the first electrode 220 and the reflective pattern 1450 aredisposed.

An organic light-emitting layer 360 and a second electrode 370 can besequentially disposed on the substrate 300 on which the bank 250 isdisposed.

Meanwhile, the reflective pattern 1450 can overlap the bank 250.

A portion of the reflective pattern 1450 in contact with the firstelectrode 220 can be positioned in the non-emission area NEA.Accordingly, the reflective pattern 1450 has an effect of improvinglight extraction efficiency without reducing an area of the emissionareas.

As shown in FIG. 16 , a transistor 405 can be disposed on a substrate300.

An insulating layer 301 and a second color filter 212 can besequentially disposed on the substrate 300 on which the transistor 405is disposed, and an overcoat layer 302 can be disposed on the insulatinglayer 301 on which the color filter 212 is disposed.

A plurality of first electrodes 220 of organic light-emitting elementsOLED can be disposed on the overcoat layer 302, and a plurality ofconnection patterns 230 can be disposed.

A bank 250 can be disposed on the overcoat layer 302 on which the firstelectrodes 220 and the connection pattern 230 are disposed.

An organic light-emitting layer 360 and a second electrode 370 can besequentially disposed on the bank 250 and the first electrodes 220.

One end portion of the connection pattern 230 can be electricallyconnected to the first electrode 220 disposed in one sub-emission area(first sub-emission area EA31 of the third emission area), and the otherend portion of the connection pattern 230 can be electrically connectedto the first electrode 220 disposed in another adjacent sub-emissionarea (second sub-emission area EA32 of the third emission area).

In other words, as shown in FIG. 16 , one end portion of one connectionpattern 230 (corresponding to the first connection pattern of FIG. 14 )can be in contact with the first electrode 220 in the first sub-emissionarea EA31 of the third emission area EA3, and the other end portion ofthe connection pattern 230 (corresponding to the third connectionpattern of FIG. 14 ) can be in contact with the first electrode 220 inthe second sub-emission area EA32 of the third emission area EA3.

The overcoat layer 302 can include holes 401 and 402 spaced apart from acontact hole CNT and formed in the non-emission area NEA.

The connection pattern disposed in the contact hole CNT can extend to bedisposed in the holes 401 and 402 of the overcoat layer 302.

The first electrodes 220 disposed around the holes 401 and 402 of theovercoat layer 302 can be connected to the connection pattern 230. Forexample, a portion of a rear surface of the first electrode 220 can bein contact with the connection pattern 230.

The connection pattern 230 not only enables the plurality ofsub-emission areas EA31 and EA32 to be driven through one circuit areabut also enables light trapped inside a display panel to be extractedout of the substrate 300 through the connection pattern 230 disposed inthe holes 401 and 402 of the overcoat layer 302. For example, since theconnection pattern 230 is disposed along the holes 401 and 402 of theovercoat layer 302 formed in one sides of the sub-emission areas EA31and EA32, the connection pattern 230 can be a reflective pattern whichchanges a direction of light on at least one inclined surface of theholes 401 and 402.

FIGS. 17 and 18 are views illustrating an example in which, when adefect occurs in a display panel having a structure of FIG. 14 , thedisplay panel is normalized.

First, referring to FIG. 17 , when a foreign material 1700 is present onat least one connection pattern (for example, a first connection pattern1431 connected to a first sub-emission area EA11 of a first emissionarea EA1), the connection pattern on which the foreign material 1700 ispresent can be cut using a laser.

As shown in FIG. 17 , a first electrode 220 disposed in the firstsub-emission area EA11 of the first emission area EA1 can be in a stateof being electrically connected to a first electrode 220, which isdisposed in a third sub-emission area EA13 of the first emission areaEA1 disposed in the same sub-row, through a reflective pattern 1450.

As such, even when the first connection pattern 1431 is cut, when thefirst emission area EA1 is in an on state, a voltage supplied from acircuit area can be applied to the first sub-emission area EA11 of thefirst emission area EA1 through a third connection pattern 1433, thefirst electrode of the third sub-emission area EA13, and the reflectivepattern 1450.

Accordingly, visibility can be prevented from being lowered because thesub-emission area does not emit light.

In addition, as shown in FIG. 18 , when a defect occurs in the firstsub-emission area EA11 itself of the first emission area EA1 due to aforeign material or the like, the connection pattern 230 and thereflective pattern 1450 positioned between the first emission area EA11and the third sub-emission area EA13 of the first emission area EA1 arecut using a laser, thereby preventing a defect from occurring in thefirst sub-emission area EA11 of the first emission area EA1.

As described above, even when one sub-emission area is disconnected froma circuit area, since one emission area is divided into at least foursub-emission areas, an area in which light is not emitted is reduced to¼ of an area in which the entirety of one emission area is disconnectedand light is not emitted, thereby improving the visibility of a displaypanel.

Further, by adding a repair pattern in a display panel having astructure of FIGS. 14 to 16 , a sub-emission area can be repairedthrough a repair process even when a foreign material is generated.

This will be described with reference to FIGS. 19 to 22 as follows.

FIG. 19 is a view illustrating a structure in which a repair pattern isadded to the structure of FIG. 14 . FIG. 20 is a cross-sectional viewalong line K-L of FIG. 19 . FIG. 21 shows views illustrating emissionstates when a display panel having the structure of FIGS. 19 and 20 isdriven before and after the display panel is repaired.

The structure of FIG. 19 can be the same as the structure of the firstto fourth emission areas EA1, EA2, EA3, and EA4 and the non-emissionarea NEA described with reference to FIG. 14 .

However, as shown in FIG. 19 , the display panel according toembodiments of the present disclosure can further include a repairpattern 1940 disposed between emission areas disposed in an (N-1)^(th)row and an N^(th) row.

Specifically, the repair pattern 1940 can be disposed between a firstemission area EA1 disposed in the (N-1)^(th) row and a first emissionarea EA1 disposed in the N^(th) row.

One repair pattern 1940 can overlap one reflective pattern 1450 arrangedin the (N-1)^(th) row and can also overlap one reflective pattern 1450disposed in the N^(th) row.

For example, as shown in FIG. 19 , a portion of one repair pattern 1940can overlap a reflective pattern 1450 disposed between a secondsub-emission area EA12 and a fourth sub-emission area EA14 of a firstemission area EA1 disposed in the (N-1)^(th) row and can also overlap areflective pattern 1450 disposed between a first sub-emission area EA11and a third sub-emission area EA13 of a first emission area EA1 disposedin the N^(th) row. In this case, one repair pattern 1940 can alsooverlap one first color filter 211.

In addition, a portion of another repair pattern 1940 can overlap areflective pattern 1450 disposed between a second sub-emission area EA22and a fourth sub-emission area EA24 of a second emission area EA2disposed in the (N-1)^(th) row and can also overlap a reflective pattern1450 disposed between a first sub-emission area EA21 and a thirdsub-emission area EA23 of a second emission area EA2 disposed in theN^(th) row.

Furthermore, as shown in FIGS. 19 and 20 , a portion of still anotherrepair pattern 1940 can overlap a reflective pattern 1450 diposedbetween a second sub-emission area EA32 and a fourth sub-emission areaEA34 of a third emission area EA3 positioned in the (N-1)^(th) row andcan also overlap a reflective pattern 1450 disposed between a firstsub-emission area EA31 and a third sub-emission area EA33 of a thirdemission area EA3 disposed in the N^(th) row. In this case, one repairpattern 1940 can also overlap one second color filter 212.

As shown in FIG. 19 , a portion of yet another repair pattern 1940 canoverlap a reflective pattern 1450 disposed between a second sub-emissionarea EA42 and a fourth sub-emission area EA44 of a fourth emission areaEA4 disposed in the (N-1)^(th) row and can also overlap a reflectivepattern 1450 disposed between a first sub-emission area EA41 and a thirdsub-emission area EA43 of a fourth emission area EA4 disposed in theN^(th) row. In this case, one repair pattern 1940 can also overlap onethird color filter 213.

As shown in FIG. 20 , the repair pattern 1940 can be disposed on anovercoat layer 302. The reflective pattern 1450 can be disposed belowthe overcoat layer 302.

Meanwhile, in the structure of the display panel shown in FIG. 19 , whena foreign material is present on one connection pattern 230, asub-emission area connected to the connection pattern 230 can benormally operated through cutting of the connection pattern 230 andrepairing using the repair pattern 1940.

For example, when a foreign material is present on a first connectionpattern 1431 and a third connection pattern 1433, which are connected tothe first and third sub-emission areas EA31 and EA33 of the thirdemission area EA3, in the connection pattern 230 positioned in theN^(th) row and an M^(th) column of FIG. 19 , in order to prevent abright spot defect from occurring in the first and third sub-emissionareas EA31 and EA33 of the third emission area EA3, the first connectionpattern 1431 and the third connection pattern 1433 can be disconnectedfrom a circuit area using a laser (Step 1).

In this case, as shown in FIG. 21 , even when a signal is applied to theN^(th) row, the first and third sub-emission areas EA31 and EA33 of thethird emission area EA3 positioned in the N^(th) row and the M^(th)column do not emit light.

Thereafter, in order to repair the first and third sub-emission areasEA31 and EA33 of the third emission area EA3, as shown in FIGS. 19 and20 , a laser can be irradiated onto the repair pattern 1940 overlappingthe second and fourth emission areas EA32 and EA34 of the third emissionarea EA3 positioned in the (N-1)^(th) row and the M^(th) column and thefirst and third sub-emission areas EA31 and EA33 of the third emissionarea EA3 positioned in the N^(th) row and the M^(th) column.

After the laser is irradiated, the repair pattern 1940 shown in FIG. 20can be connected to the reflective patterns 1450 disposed below therepair pattern 1940.

Since a first electrode 220 disposed to correspond to the second andfourth sub-emission areas EA32 and EA34 of the third emission area EA3disposed in the (N-1)^(th) row and the M^(th) column is in a state ofbeing in contact with the repair pattern 1940 overlapping the second andfourth emission areas EA32 and EA34 of the third emission area EA3positioned in the (N-1)^(th) row and the M^(th) column and the first andthird sub-emission areas EA31 and EA33 of the third emission area EA3positioned in the N^(th) row and the M^(th) column, the first and thirdsub-emission areas EA31 and EA33 of the third emission area EA3positioned in the N^(th) row and the M^(th) column can be electricallyconnected to a circuit area for driving the third emission area EA3positioned in the (N-1)^(th) row and the M^(th) column.

Accordingly, as shown in FIG. 21 , after repairing is performed (afterStep 2), when the third emission area EA3 disposed in the (N-1)^(th) rowand the M^(th) column is driven, the first and third sub-emission areasEA31 and EA33 of the third emission area EA3 disposed in the N^(th) rowand the M^(th) column can also be driven.

For example, even when a foreign material is generated on the connectionpattern 230, all sub-emission areas can emit light without sub-emissionareas that do not emit light.

A structure in which one repair pattern 1940 per four sub-emission areasis disposed has been mainly described with reference to FIGS. 19 to 21 ,but embodiments of the present disclosure are not limited thereto.

FIG. 22 is a view illustrating a structure in which two repair patternsper four sub-emission areas are disposed in the structure of FIG. 14 .FIG. 23 is a cross-sectional view along line M-N of FIG. 22 . FIG. 24shows views illustrating emission states when a display panel having thestructure of FIGS. 22 and 23 is driven before and after the displaypanel is repaired.

The structure of FIG. 22 can be the same as the structure of each of thefirst to fourth emission areas EA1, EA2, EA3, and EA4 and thenon-emission area NEA1 described with reference to FIG. 14 .

However, as shown in FIG. 22 , the display panel according toembodiments of the present disclosure can further include a first repairpattern 2241 and a second repair pattern 2242 disposed between emissionareas disposed in an (N-1)^(th) row and an N^(th) row.

Specifically, the first repair pattern 2241 and the second repairpattern 2242 can be disposed between a first emission area EA1 disposedin the (N-1)^(th) row and a first emission area EA1 disposed in theN^(th) row.

A portion of the first repair pattern 2241 overlapping a first colorfilter 211 can overlap a portion of a first electrode 220 correspondingto a second sub-emission area EA12 of a first emission area EA1 disposedin the (N-1)^(th) row and an M^(th) column. Another portion of the firstrepair pattern 2241 overlapping the first color filter 211 can overlap aportion of a first electrode 220 corresponding to a first sub-emissionarea EA11 of a first emission area EA1 disposed in the N^(th) row andthe M^(th) column.

In addition, a portion of the second repair pattern 2242 overlapping thefirst color filter 211 can overlap a portion of a first electrode 220corresponding to a fourth sub-emission area EA14 of the first emissionarea EA1 disposed in the (N-1)^(th) row and the M^(th) column. Anotherportion of the second repair pattern 2242 overlapping the first colorfilter 211 can overlap a portion of a first electrode 220 correspondingto a third sub-emission area EA13 of the first emission area EA1disposed in the N^(th) row and the M^(th) column.

A portion of one first repair pattern 2241 positioned in a non-emissionarea NEA around a second emission area EA2 is can overlap a portion of afirst electrode 220 corresponding to a second sub-emission area EA22 ofa second emission area EA2 disposed in the (N-1)^(th) row and the M^(th)column. Another portion of the first repair pattern 2241 overlapping thefirst color filter 211 can overlap a portion of a first electrode 220corresponding to a first sub-emission area EA21 of a second emissionarea EA2 disposed in the N^(th) row and the M^(th) column.

In addition, a portion of one second repair pattern 2242 positioned inthe non-emission area NEA around the second emission area EA2 canoverlap a portion of a first electrode 220 corresponding to a fourthsub-emission area EA24 of the second emission area EA2 disposed in the(N-1)^(th) row and the M^(th) column. Another portion of the secondrepair pattern 2242 can overlap a portion of a first electrode 220corresponding to a third sub-emission area EA23 of the second emissionarea EA2 disposed in the N^(th) row and the M^(th) column.

A portion of the first repair pattern 2241 overlapping a second colorfilter 212 can overlap a portion of a first electrode 220 correspondingto a second sub-emission area EA32 of a third emission area EA3 disposedin the (N-1)^(th) row and the M^(th) column. Another portion of thefirst repair pattern 2241 overlapping the second color filter 212 canoverlap a portion of a first electrode 220 corresponding to a firstsub-emission area EA31 of a third emission area EA3 disposed in theN^(th) row and the M^(th) column.

In addition, a portion of the second repair pattern 2242 overlapping thesecond color filter 212 can overlap a portion of a first electrode 220corresponding to a fourth sub-emission area EA34 of the third emissionarea EA3 disposed in the (N-1)^(th) row and the M^(th) column. Anotherportion of the second repair pattern 2242 overlapping the second colorfilter 212 can overlap a portion of a first electrode 220 correspondingto a third sub-emission area EA33 of the third emission area EA3disposed in the N^(th) row and the M^(th) column.

A portion of the first repair pattern 2241 overlapping a third colorfilter 213 can overlap a portion of a first electrode 220 correspondingto a second sub-emission area EA42 of a fourth emission area EA4disposed in the (N-1)^(th) row and the M^(th) column. Another portion ofthe first repair pattern 2241 overlapping the third color filter 213 canoverlap a portion of a first electrode 220 corresponding to a firstsub-emission area EA41 of a fourth emission area EA4 disposed in theN^(th) row and the M^(th) column.

In addition, a portion of the second repair pattern 2242 overlapping thethird color filter 213 can overlap a portion of a first electrode 220corresponding to a fourth sub-emission area EA44 of the fourth emissionarea EA4 disposed in the (N-1)^(th) row and the M^(th) column. Anotherportion of the second repair pattern 2242 overlapping the third colorfilter 213 can overlap a portion of a first electrode 220 correspondingto a third sub-emission area EA43 of the fourth emission area EA4disposed in the N^(th) row and the M^(th) column.

As shown in FIG. 23 , the first and second repair patterns 2241 and 2242can be disposed below an overcoat layer 302. The first electrode 220disposed to correspond to each sub-emission area can be disposed on theovercoat layer 302.

Meanwhile, in the structure of the display panel shown in FIG. 22 , whena foreign material is present on one connection pattern 230, asub-emission area connected to the connection pattern 230 can benormally operated through cutting of the connection pattern 230 andrepairing using the first and second repair patterns 2241 and 2242.

For example, when a foreign material is present on a first connectionpattern 1431, which is connected to the first sub-emission area EA31 ofthe third emission area EA3, in the connection pattern 230 positioned inthe N^(th) row and the M^(th) column, a bright spot defect can occur inthe first sub-emission area EA31 of the third emission area EA3. Inorder to prevent the bright spot defect, the first connection pattern1431 can be disconnected from a circuit area using a laser (Step 1).

In this case, as shown in FIG. 24 , even when a signal is applied to theN^(th) row, the first sub-emission area EA31 of the third emission areaEA3 positioned in the N^(th) row and the M^(th) column does not emitlight.

Thereafter, in order to repair the first sub-emission area EA31 of thethird emission area EA3, as shown in FIGS. 22 and 23 , a laser can beirradiated onto the first repair pattern 2241 overlapping each of thefirst electrode 220 disposed to correspond to the second sub-emissionarea EA32 of the third emission area EA3 positioned in the (N-1)^(th)row and the M^(th) column and the first electrode 220 disposed tocorrespond to the first sub-emission area EA31 of the third emissionarea EA3 positioned in the N^(th) row and the M^(th) column.

After the laser is irradiated, the first repair pattern 2241 shown inFIG. 23 can be connected to the first electrodes 220 disposed on thefirst repair pattern 2241.

Since the first electrode 220 disposed to correspond to the firstsub-emission area EA31 of the third emission area EA3 positioned in the(N-1)^(th) row and the M^(th) column and the first electrode 220disposed to correspond to the first sub-emission area EA31 of the thirdemission area EA3 positioned in the N^(th) row and the M^(th) column arein a state of being in contact with a repair pattern 1940, the first andthird sub-emission areas EA31 and EA33 of the third emission area EA3positioned in the N^(th) row and the M^(th) column can be electricallyconnected to a circuit area for driving the third emission area EA3positioned in the (N-1)^(th) row and the M^(th) column.

Accordingly, as shown in FIG. 24 , after repairing is performed (afterStep 2), when the third emission area EA3 disposed in the (N-1)^(th) rowand the M^(th) column is driven, the first sub-emission area EA31 of thethird emission area EA3 disposed in the N^(th) row and the M^(th) columncan also be driven.

For example, even when a foreign material is generated on the connectionpattern 230, since one emission area is divided into at least foursub-emission areas and an area of each sub-emission area is smaller thanan area of one emission area, even when a sub-emission area disposed ina corresponding row is repaired to emit light when another adjacent rowis in an on state, it is possible to reduce a possibility of a descreasein visibility.
